Interesting AS program combinations

I have both Spy Sweeper and MS Antispyware, which have these brief comparison features:
- Resident real-time scanner memory load of MS AS is about 17 MB.
- Resident real-time scanner memory load of Spy Sweeper is about 27 MB.
- SpySweeper incorporates the 'Shields' concept - MS AS does not.
- Some of the enabled 'Shields' remain effective even when Spy Sweeper is shut down.

I'm currently running this combination:
- SpySweeper 'Common Ads Shield' was enabled, and Spy Sweeper shut down.
- Only MS AS is configured to run at Windows startup.

The results:
- MS AS real-time scanner is enabled, with it's light memory load.
- Whenever a site ad is detected, the Spy Sweeper 'Common Ads Shield' is triggered, killing the ad - even though Spy Sweeper is not resident in memory.

Other combinations are possible, though not all Spy Sweeper 'Shields' remain effective when Spy Sweeper is shut down.

I found this interesting - hope you do too.
